srncrr'rciirrou forming part of Letters Patent No. 617,511, datedJanuary 10, 1899. Application filed March 10, 1897. Serial No. 626,804.(N6 man.)

To all whom it may concern:

Be it known that 1, WILLIAM C. PEIROE,

of the city and county of. Providence and.

State of Rhode Island, haveinvented a new and useful'lmprovement inRoving-Machines; and I hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification.

Roving-machines, also called Speeders, by which the initial twist is putinto the carded and drawn-out fiber to prepare the ings below thespindles may be made of any requiredlength and may be made to drive anydesired number of spindles.

The bobbins in roving-machines are driven at constantlyvarying speedsfrom shafts which have to reciprocate with the bobbins. The size ofthese shafts is limited, because they must be supported in bearings onone side of the spindles and drive the bobbins by skew-beveled gears.

Heretofore the shafts for driving all the bobbins in a roving machinewere driven through the compound from the driving-head of the machine.With the increase of the length of the machine and the number ofspindles the bobbins of which have to be driven the load upon the bobbindriving shafts and the train of gears transmitting the motion from thecompound gear to the bob bin-driving shaft has been so much increasedthat the gears frequently break and soon wear out.

The object of this invention is to construct a roving-machine of two ormore lengths or sections and to drive each section by a separate trainof gears.

Another object of this invention is to counterbalance the reciprocatingparts of one section of a roving-machine with another section, while thebobbin-shafts of each section are driven by a separate train of gears.

To this end theinvention consists in the peculiar and novel constructionwhereby the bobbin-driving shafts are divided into two or more sections,a back shaft is connected by gears with the compound, the bobbin-drivingshafts of the first section are connected by a swinging train of gearswith the compound, and the bobbin-driving shafts of the other section orsections which are connected by a swinging train of gears with the backshaft, so that the power is transmitted from the compound to eachsection by separate trains of gears, as will be more fully set forthhereinafter.

Figure 1 is a front view of a speeder, showing the right-hand section ofthe bobbins at the upper traverse when winding on the bottom of thebobbins'and the left-hand section at the lower traverse winding on thetop of the bobbins. The figure is contracted lengthwise by cutting outthe portions of the speeder between the first two and the last twospindles of each section. Fig. 2 is a rear view of the driving end of aspeeder. Fig. 3 is a rear view of the speeder condensed lengthwise,'theportion on the left-hand of the figure showing the end of the firstsection, the middle portion the beginning of the second section, and theright-hand portion the end of the second section. Fig. i is an end viewof the driving-head of the speeder, the end plate or cover being removedto more clearly show the gears contained in the end frame. Fig. 5 is atransverse section of the speeder near the end of the first part of themachine. Fig. 6 is a side view of the rack used in the first part of themachine to operate the bolsterrail. on the second part of the machine.

Similar numerals and letters of reference indicate corresponding partsin all the figures.

Inthe drawings, A indicates the head-frame at the driving end of themachine; B, the opposite end frame; 0, one of the intermediate frames;D, the drawing-rolls; F F, the fiiers, secured to the upper ends of thespindles; G G, the bobbins; H, the step-rail; I, the reciproeatingbolster-rails.

. I have designated in the drawings the first half of the machine,extendingfrom thehead- Fig. 7 is a side view of the rack used Ico frameA to the middle of its length, as a, and

the other-half, extending from the middle to the end frame B, as b, anduse this designaspeed of the bobbins.

tion for the two halves of the machine. All the spindles in bothsections a and b are supported in step-bearings, preferably secured tothe step-rail H, which extends the whole length of the machine. Eachspindle is provided with a bevelgear 1 which engages with a bevel-gear 2on the shaft 3 for the front row of spindles or on the shaft 4. for therear row of spindles. These shafts 3 and4extend the whole length of themachine.

The bolster-rails of both sections a and Z) are provided with bracketsforming the bolster-supports for the spindles and the support for one ofthe shafts 5. A collar 6 turns on the bolster and is connected with thebobbin G. A skei -gear forms part of the collar 6 and engages with askew-gear 7 on one of the two shafts 5. Both the bolster-rails I havesecured to them the brackets 8 8. In section a the brackets 8 aresecured to the racks 0, (shown in Fig. 6,) while in section Z) thebrackets 8 are secured to the rack -frame 10 (Shown in Fig. '7.)

The mechanism for operating the first half or section a of the machineis the usual mechanism used for driving the spindles and bobbins ofrovingmachines. The driving-shaft 11 has on the outside of thehead-frame A the tight and loose pulleys 12. The shaft extends into theframe and has secured to it the gear 13, which through an intermediategear communicates motion to the gear 14, secured to the shaft of theupper cone-pulley 15. A gear on the shaft of the upper eone(shown inbroken lines in Fig. 2) communicates motion to the drawing-rolls. One ofthe gears of the compound gears 10 is secured to the driving-shaft 11,and to the sleeve 17 of the compound the gear 18 is secured, whichcommunicates motion through the usual set of gears, journaled in aswinging frame, to the shafts 5 5, by which the bobbins are driven. Thelarge gear of the compound 16 is connected, through the pinion 19 andconnecting-gears, with the cone 20, which is driven by means of the belt21 from the cone 15. The usual shipper mechanism is used for regulatingthe variation of the On the shaft carrying the pinion 19 is secured abeveled pinion which gears with the bevel-gear 23 on the end of avertical shaft, at the lower end of which the beveled pinion 24:connects with one or the other of two bevel-gears secured to theshipper-shaft 25, the longitudinal motion of which is controlled by thecop-builder mechanism. The long pinion 26, through the change-gear 27and the gears indicated in broken lines in the head-frame A, transmitsthe alternately right-hand and left-hand motion of the shipper-shaft 25to the pinion-shaft 28, and the pinions of this shaft engage with v the1'acks'9 to impart the reciprocating m0- tion to the bolster-rail I andthe bobbins in section a of the machine.

The pinion-shaft 28 extends through the whole length of the machine andimparts reciprocating motion to both the bolster-rails; but the rack 9is in front of the pinions and the rack of the rack-frame 10" is in therear of the pinions, so that the weight of the bolster-rail I, thebolsters, the bobbins,with their varying loads, and the bobbin-drivingmechanism of the section CL is supported on one side of the pinions andthe shaft 28, to which they are secured, and the bolster-rail I ofsection b, with its fixed as well as its varying load, is supported onthe opposite side of the pinions and the shaft 28, the weight of onecounterbalaneing the other.

As above described, any of the usual forms of mechanism used to drivethe bobbins of a roving-frame or speeder maybe used to drive the bobbinsof section a of my improved machine. The mechanism selected to show theapplication of my invention (shown in the drawings and hereinbeforesufficiently described to enable one skilled in the art to understandthe same) contains as one of its essential elements the sleeve 17 of thecompound 16. From this sleeve 17, through the gear 18 and a train ofgears journaled in What is usually termed the swing, motion is impartedto the bobbins of section a. To transmit this motion with the variationsin speed to the bobbins of section 7), I place on the sleeve 17 the gear20, which is an exact duplicate of the gear 18. I support a back shaft30 in suitable bearings and extend the same through the length ofsection a and into section b of the machine. To this back shaft 30 Isecure the gear 31, which, like the gear 29, is an exact duplicate ofthe gear 18, and engage it with the gear 29 on the sleeve 17 of thecompound, and on the same back shaft 30, in section b, Iseeu're the gear32, so as to mesh with the gear 33 on the short shaft 34:, which is thepivotal support of the swing 35. (Indicatedin broken lines in Fig. 5.)As the gears 29, 31, 32, and 33 are all of the same diameter and havethe same number of teeth as the gear 18 the gear 33 moves at exactly thesame speed and in the same direction as does the gear 18. From the gear33 the motion is transmitted, through the usual gears journaled in theswing or swinging frame 35, as indicated in broken lines in Fig. 5, tothe shafts 5 5, from which the bobbins are driven. The swing or swingingframe 35 is in all respects like the swing 35, (shown in Fig. 2,)pivotally connected with the driving-shaft 11 close to the head-frameand both swing up and down with the bolster-rail, transmitting motion tothe bobbins of both the sections a and b and at the same speed, bothsections being controlled by the same speed-changing mechanism.

The spindles are driven, usually, at a constant speed from thedriving-shaft 11,to which, within the head-frame A, the gear 36 issecured, which engages with the gear 37 and transmits the motion to thegear 38 on the shaft 4., by which the rear row of spindles are driven,and the gear 38 engages with the gear 39 on the shaft 3, by which thespindles of the front row are driven.

The bolster-railsl of both sections and the step-rail H, with thedriving-gears connected with these rails, are inclosed in the casings40, provided with the doors 41, each one of these doors giving access tothe driving-gears connected with two spindles.

The modern tendency is to lengthen out spinning and similar machines, soas to .increase their production. In many instances it becomes importantto extend the rovingmachine or speeder across the whole width of a mill,and in such cases it is desirable to place the main driving-shaft on oneside, so as to leave the rest of the room free from all obstructions.I11 the old form of these machines the bolster-rail was required toextend the whole length of the machine, and the machine could not bematerially lengthened without increasing the dimension and the weight ofthe bolster-rail. A machine constructed after my invention may be madeof any length desired, and two, four, or more sections, each of moderatelength, used and connected with the back shaft, so that thebolster-rails of one half the number of sections in the machine willcounterbalance the bolster-rails of the other half of the number ofsections. All the bobbins in the longest machine will be driven from oneend of the machine, and the changes in speed of all the bobbins will beregulated by the speed-regulating mechanism in the first section next tothe drivinghead of the machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a roving-machine, the combination of thefollowing instrumentalities: a bolster and bobbin support divided intotwo or more lengths or sections, independent bobbin-driving mechanismfor each section, mechanism comprising a compound for driving thebobbins at varying speed, a swinging train of gears for each section,and connections between the compound and the swinging trains of gears ofthe sections; whereby the varying speed of the compound is transmittedto each section by a separate train of gears, as described. I

2. In a roving-machine, the combination with two sets of rails and twosets of bobbindriving mechanism one for each rail, of a compoundmechanism for varying the speed of the bobbins, a train of gearsconnecting the compound with the bobbin-driving mechanism of one rail,aback shaft connected with the compound by suitable gears, a train ofgears connecting the backshaft with the bobbin-driving mechanism of theother rail, and mechanism, substantially as described, for reciprocatingthe two rails; whereby the weights carried by the two rails arecounterbalanced one by the other and the bobbins of the two sections aredriven each by a separate train of gears, as described.

3. In combination, a roving-frame divided lengthwise into two sections,each section provided with a bolster-rail and bobbin-driving mechanism,traversing mechanism for moving the bolster-rails in oppositedirections, a compound for varying the speed of the bobbins, two gearson the sleeve of the compound, a swinging train of gears connecting oneof the gears on the sleeve of the compound with the bobbin-drivingmechanism of one section, a swinging train of gears connecting with thebobbin-driving mechanism of the other section, and a shaft connectingthe train of gears of the second section with the other gear on thesleeve of the compound; whereby each section is driven by an independenttrain of gears, and the speed of the bobbins of each section iscontrolled by the compound, as described.

4. In a roving-machine, the combination with the driving'mechanism andthe compound for regulating the varying speed of the bobbins, of two ormore sections of bolsterrails each provided with a separatebobbindriving mechanism, a swinging train of gears connecting a gear onthe sleeve of the compound with the bobbin-driving mechanism of onerail, a back shaft driven from the sleeve of the compound, and a trainof gears connecting the back shaft with the bobbin-driving mechanism ofthe other section or sections, racks connected with the sections ofbolsterrails, a longitudinal shaft provided with pinions engaging withthe racks of the different sections of the bolster-rails on oppositesides; whereby a series of sections of a rovingmachine may each bedriven by a separate train of gears controlled by the compound, and theweight of one section counterbalanced by another section, as described.

In witness whereof I have hereunto set my hand.
